Trees add beauty, shade, and value to your property, but they can also pose serious safety risks when weakened by age, disease, or storm damage. While most trees appear healthy from the outside, hidden structural problems can lead to falling limbs or even complete tree failure during severe weather.
That’s where a tree risk assessment comes in. This professional evaluation identifies potential hazards before they cause costly damage or injury. Whether you own a single-family home, manage commercial properties, or oversee community spaces, knowing the condition of your trees is an essential part of responsible property care.
In this guide, you’ll learn what a tree risk assessment is, how it works, and why every Tennessee property owner should schedule one—especially before storm season.

A tree risk assessment is a professional evaluation that determines the likelihood of a tree or its parts failing and causing damage or injury. It’s performed by a certified arborist who inspects each tree for structural, biological, and environmental risk factors.
The goal is to answer three key questions:
Based on the answers, the arborist assigns a risk rating and provides recommendations such as pruning, cabling, or removal.
Many homeowners assume that a tree is safe if it looks healthy. In reality, many dangerous trees show few visible symptoms until failure occurs.
A tree that looks fine one year can become dangerous the next due to hidden decay or severe weather stress. Regular assessments ensure you’re never caught off guard.
While it’s wise to inspect trees regularly, certain times make assessments especially important.
In East Tennessee, it’s smart to schedule an inspection at least once a year, preferably before spring storms or winter freeze cycles.
A certified arborist follows a systematic process to evaluate each tree’s health, structure, and risk level. The International Society of Arboriculture (ISA) has standardized methods known as the Tree Risk Assessment Qualification (TRAQ) system.
The arborist begins by visually examining the tree from the ground up. They look for signs of decay, insect infestation, cracks, or poor structure. The canopy, trunk, and root system are each assessed for visible weaknesses.
Key indicators include:
If visible symptoms suggest internal issues, the arborist may use specialized tools such as:
These tools help detect hidden weaknesses that can’t be seen from the surface.
Each tree is then rated using three main factors:
Combining these factors results in a risk category:
This clear scale allows property owners to prioritize actions based on urgency.
Finally, the arborist provides a written report outlining specific recommendations such as:
This plan helps you make informed, cost-effective decisions about each tree on your property.
Only trained professionals should perform formal tree risk assessments. Certified arborists have specialized education and credentials to identify risks accurately.
Hiring a qualified expert ensures you receive precise evaluations and actionable recommendations that truly protect your property.

Not all risks are immediately visible. During a risk assessment, professionals evaluate a wide range of potential hazards.
Each factor is analyzed to understand how it might contribute to future failure.
After assessment, trees are placed into risk categories that guide maintenance decisions.
The tree shows minimal defects and no significant targets nearby. Regular maintenance is recommended.
Minor defects exist, but failure is unlikely in the near term. Pruning or soil care may reduce risk.
Significant structural weaknesses or decay are present. The tree should be monitored closely or partially removed.
The tree poses immediate danger due to instability, disease, or location near high-value targets. Removal is usually necessary.
A written risk report helps you prioritize work based on both safety and budget considerations.
Most residential properties benefit from an annual inspection, especially before storm season. However, more frequent assessments are recommended if:
Routine evaluations catch changes early, allowing for preventive action rather than emergency response.
Ignoring potential tree hazards can lead to severe consequences.
Removing a fallen tree after it causes damage can cost thousands—much more than preventive pruning or inspection. Insurance may not cover costs if neglect is proven.
Falling branches or uprooted trees can cause serious injury or death. Risk assessments help prevent accidents before they happen.
Property owners can be held liable if a neglected tree damages a neighbor’s property or injures someone. Documented assessments show that you’ve taken reasonable precautions.
Strong storms are common in Tennessee, and weakened trees can easily fall on homes, vehicles, or power lines. Preventive inspection protects your investments.
In regions like East Tennessee, where storms and heavy winds are frequent, tree risk assessments play a crucial role in storm safety planning.

The price depends on the number of trees, their size, and the complexity of the property. On average:
While costs vary, assessments often save homeowners thousands by preventing emergency removals or structural damage.
Once your assessment is complete, ongoing maintenance ensures your trees stay healthy and low-risk.
These steps keep your property safe while extending the life of your trees.
Q: How long does a tree risk assessment take?
Most assessments take between 30 minutes and 2 hours per tree, depending on size and condition.
Q: Will the arborist always recommend removal?
No. In many cases, pruning, cabling, or soil treatments can stabilize trees without removal.
Q: Are assessments required by insurance companies?
Some insurers may require them after storm damage or before issuing coverage for high-risk properties.
Q: Can risk assessments detect hidden decay?
Yes. Professionals use advanced tools and experience to identify internal issues invisible to the eye.
A tree risk assessment is one of the smartest investments a property owner can make. It provides peace of mind, reduces liability, and ensures your trees remain both safe and healthy for years to come.
